AviSynth and Filter Order

[sambat]

I read that when using AviSynth, the order of processing should be:
Cropping
Spatial Filtering
Temporal Filtering
Resizing

I know what the first and last are, but Space and Time ??
Anyone offer an opinion on the order listed or define examples of space and time filters.

Spacial filtering: filters that involve individual frames (2d noise reduction, sharpen, hsv, etc.)
Temporal filtering: filters that involve multiple frames (3d noise reduction, spot removal, deshaking, etc.)

Please, what's a 2d/3d noise?

2d: width (x) and height (y) of a frame
3d: width (x) and height (y) of a frame + earlier and later frames (z)
